AI 中文摘要
本文研究了支配多体系统动力学的一体和二体$\boldsymbol{\frak{su}(n)}$哈密顿量,包括集体中微子振荡。我们首先分析代数结构$\boldsymbol{\frak{u}(n^N)}$,构建代数的乘积结构,并利用该结构推导出算子期望值、Rényi熵和Wigner函数的通用表达式。通过对BBGKY层级进行截断,我们开发了一种系统方法,可在经典计算机上实现超越平均场的多项式缩放。
英文摘要
A one- and two-body $\mathfrak{su}(n)$ Hamiltonian governing the dynamics of many systems, including collective neutrino oscillations, is investigated. We start by analyzing the algebraic structure($\mathfrak{u}(n^N)$), formulate a product structure of the algebra, and utilize this to construct generic expressions for operator expectation values, Rényi Entropy, and Wigner Functions. Performing BBGKY hierarchy truncation we develop a systematic methodology for going beyond the mean field with polynomial scaling on a classical computer.
